机载LiDAR技术在柬埔寨1∶2000地形图测量中的应用
|
摘要
结合柬埔寨项目1∶2000地形图测绘项目,介绍机载激光雷达技术在植被茂盛的密林地区测绘中的应用,重点介绍了项目实施中技术方案的制定和数据后处理的过程。试验表明,机载激光雷达技术可以解决大面积森林覆盖地区、沙漠、沼泽、草原等困难地区及其他无法到达或危险区域的测绘工作,能够大量减少人工成本并获取丰富的地形测量成果,成果精度满足相关规范要求。
With practice of the surveying of 1∶ 2000 topographic map in Cambodia project,application of the aircraft- carrying laser radar technology in surveying in the region where vegetation is flourishing and dense. Preparation of the technical proposal and course of the post data processing in the project implementation are introduced especially. The tests prove that the aircraft- carrying laser radar technology can realize the surveying and mapping of the regions where forests cover in a large area,deserts,marshland and grass land,etc and it is difficult to reach and perform the surveying or the area where is dangerous,and it is impossible to survey. The technology can largely reduce manpower cost and obtain abundant topographic surveying results. The surveying precision satisfies the requirements of relevant specifications.
